Abstract

The invention discloses a simulation device for a vertical excavation mechanism of karst water. The simulation device comprises an excavator, a transport cart and a loader water pump. The vertical excavation aim is to mainly detect the corrosion speed and a water flow field of a karst cave. The specific operation comprises the following steps: before drilling, firstly, carrying out preliminary statistics according to geological exploration data to determine whether the karst caves in part of drill holes are in beads-shaped distribution or not and the distribution range of the karst caves, or sampling according to detailed exploration to determine whether the karst caves exist in to-be-drilled piers or not; secondly, preliminarily determining whether the karst caves exist in a constructionarea or not according to near constructed pile foundations. According to the simulation device for the vertical excavation mechanism of the karst water, data of rock components, structure and influence of environment on karst corrosion, are obtained by the simulation device; in addition, the karst water can be detected by a three-dimensional finite difference underground water current simulation program and a three-dimensional solute transporting module to obtain a distribution diagram of pollution sources and point-to-point repair is facilitated.

Description

technical field [0001] The invention relates to the technical field of karst tunneling simulation equipment, in particular to a simulation device for vertical tunneling mechanism of karst water. Background technique [0002] The water richness of the karst aquifer is generally strong, but the water content is extremely uneven. Because karst water does not evenly spread throughout the distribution range of the soluble rocks, but is buried in the dissolution cracks and caves of the karst rocks, the same karst aquifer is often within the same elevation range, or in the same area, or even a few meters apart, the water-rich The difference can be tens to hundreds of times. Contents of the invention [0003] The purpose of the present invention is to provide a simulating device for the vertical excavation mechanism of karst water, so as to solve the existing technical defects and technical requirements that cannot be met. [0004] In order to achieve the above object, the prese...
